Parser syntax error for bang comment variable (/*! SELECT 1 INTO @v) */)

## Bug Report

### 1. Minimal reproduce step
Use `Parser.ParseSQL` on the following string:

```sql
/*! SELECT 1 INTO @v */;
```

### 2. What did you expect to see?
This is valid MySQL and should not result in a syntax error.
The example is simplified from what is output by mysqldump:
```sql
/*!50717 SELECT COUNT(*) INTO @rocksdb_has_p_s_session_variables FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = 'performance_schema' AND TABLE_NAME = 'session_variables' */;
```

### 3. What did you see instead
An error is returned with this content:
```
line 1 column 20 near "@v */;"
```

### 4. What is your TiDB version?
